JOSEPH E. J. GOODLETT, OF MEMPHIS, TENNESSEE.

MACHINE FOB IMPREGNATING STOCK FOODS.

Specification of Letters Patent.

Patented Jan. 16, 1911.

Application filed October 28, 1909. Serial No. 525,021.

To all whom it 'may concern:

Be it known that I, JOSEPH E. J. GOOD- Lnfr'r, a citizen of the United States, residing at Memphis, in the county of Shelby and State of Tennessee, have invented certain new and useful Improvements in Machines for Impregnating Stock Foods, of which the following is a specification.

My invention relates to improvements in machines for impregnating stock-foods with molasses, the primary object of the invention being to provide a generally improved` machine or apparatus for this purpose of simple, cheap, and efficient construction adapted to thoroughly atomize hot molasses and mix or incorporate the same with stockfood, such for example, as alfalfa, corn, oats and other grains.

The invention relates more particularly to an improved atomizing nozzle adapted to atomize the hot molasses as received from the boiling kettle by means of compressed air and distribute and project the atomized molasses into a stream of falling stock-food as the latter passes from the storage tank into the mixer of the improved apparatus.

The process of treating stock-foods herein described but not claimed, is made the subject matter of a divisional application, filed November 30, 1910, Serial No. 591,995.

Vith the above mentioned ends in View, the invention consists in the novel construction, arrangement, and combination of parts, hereinafter described, illustrated in one of its embodiments in the accompanying drawings, and particularly pointed out in the appended claims.

Referring to the drawings forming a part of this specification, Figure 1, is a front elevation of a machine or apparatus constructed in accordance with this invention. Fig. 2, an end or side elevation of the same. Fig. 3, an enlarged detailed top plan view of the improved atomizing nozzle, a portion of its walls being broken away for the purpose of clearer illust-ration of the parts. Fig. 4, an end view of the same. Fig. 5, a cross sectional view of the same taken through line 55 of Fig. 3. Fig. 6, a crosssectional view of the mixer taken through line 6-6 of Fig. 1.

Similar numerals of reference designate like parts throughout all the figures of the drawings.

The improved machine or apparatus, in its present embodiment, comprises a storage ,vided with a longitudinal bin 1, into which the stock-food to be treated is first placed, and a molasses heating kettle or tank 2, to receive the molasses to be heated and atomized as hereinafter described. The storage bin 1, is provided with a depending hopper portion 1a, provided at its lower end with an inclined shaker board or plate 3, adapted, when the machinery is started, to be reciprocated by means of an eccentric shaft 4t, and connecting rod 5. hen the machinery is in operation the shaker plate 5, is adapted to distribute and feed the stock-food in a thin longitudinally extending stream along the edge 3, of the plate where it falls into one end of the mixer 6, to be heated and conveyed as hereinafter described.

After the molasses has been properly heated in the kettle or tank 2, and the machinery started, it is conducted through the conduit pipe 7, by opening the valve 8, and the hot molasses is I ermitted to enter the longitudinally exten ing chamber 9, of the valve body 10, carried upon the end of the conduit pipe 7. r1`he valve body 10, extends horizontally the full width of the adjacent end of the mixer 6, and is provided with 'a longitudinally extending nozzle portion 10, adjacent to the falling stream of food to be treated, and said nozzle portion is adapted to distribute and project the atomized molasses into the falling stream of stock-food or feed.

rlhe character and quantity of the atomized stream of molasses passing out of the longitudinal slot 11, 'of the nipple portion 10b, is controlled and regulated by means of a longitudinally extending hollow wedge shaped or tapered movable valve 12, mounted in ways 13, within the valve body 10, said movable valve having its tapered portion 12a, adapted to be seated within the longitudinal recess or channel portion 11, of the valve body. The movable valve 12, is proslot 13, at the apex of its tapered portion 12a; said slot registering with and being adjacent to the longitudinal slot 11, in the nozzle portion of the valve body and communicating with a longitudinally extending air chamber 14, within the movable valve. The movable valve 12, is provided at its rear with an air inlet pipe-stem 15, extending through and slidably mounted in the rear portion of the valve body. The air inlet pipe or stem 15, is connected to a suitable air pipe or hose with threaded openings through which the movable valve 12, may be inserted or re moved, said thread openings being closed by means of threaded plugs 16.` The movable valve 12 is adapted to be' moved or shifted to and from its open or closed positions by means of threaded thumb bolts 17, extending rearwardly and mounted in suitable threaded openings in the rear portion of the valve body as shown. The slidably mounted air inlet pipe 15, preferably extends through an exteriorly threaded boss 18, adapted to contain a packing-gland retained in position by means of a packing nut 19.

The mixer 6, contains a V-shaped trough 20, surrounded by a series of steam heating pipes 21. The stock-food after being subjected to the spray of molasses and after falling into thc end of the mixer, is carried along in the V-shaped trough by means of a screw conveyer 22, mounted on a driving shaft 23. The stock-food as carried along in the trough 20, is heated from the steam pipes 21, and the heat generated in the chamber 24, intermediate the trough 20, and the walls of the mixer 6, is adapted to communicate with the receiving end of conveyer trough 20, in the present instance, by means of a conduit pipe 25 having its end i 25a, intersecting the front wall of the mixer,

asshown most clearly in Fig. 6, of the drawings. An apron 26, is preferably formed in the trough 20, above the screw conveyer 22, and the hot air is drawn from the receiving end of the mixer through the stream of falling feed toward the discharge end of the mixer by 'means of a suction trunk 27, communicating with a suction or blower fan in the fan casing 28. The cold air passes into the u l 7 and is then heated by passing over and about the steam pipes 21, where it is heated and utilized as above described. One end of the shaft 23, is provided with aldriving pulley 29, adapted to carry a belting communicating with a suitable source of power and the other end of the driving shaft is provided with a sprocket wheel 30, carrying a sprocket chain 31, passing overa second sprocket wheel32, above, which latter operates a suitable elevatorchain or belt in the vertically arranged elevator boots 33. The shaft 23 is provided with a second sprocket wheel adjacent the driving pulley .provided with a vertical feed box or spout 37,*which receives the feed from the discharge end of the mixer 6, above. The feed as received at the receiving end of the conveyer box 36, is carried by the screw conveyer to the opposite end of the conveyer box where it is discharged and -falls through a vertical spout or box 38, into the receiving end of a second conveyer box 39. The feed as discharged in this conveyer. box is conveyed by a screw conveyer similar to those above described and the opposite end of the conveyer box 39, where it is discharged through a discharge spout 40, intersecting the lower ends of the elevator boots 33. 'The screw conveyer in the conveyer box 39, is operated by a sprocket wheel 41,-carrying a sprocket chain 42, passing over a sprocket wheel 43, on the end of the screw conveyer in the conveyer box above.

The fan in the fan casing 28, is adapted to be driven by a pulley 44, and to discharge cold air through an upwardly extending air discharge pipe 45. Said air discharge pipe terminating at its upper end -in 'outlet branches 45a and 45h. The upperv branch 45a, intersecting the spout37 and discharging cold air therein. The lower outlet branch 45h, intersects a cold air conduit- 46, extending ralong the spout or box 36, and intersecting the upper end of the discharge spout or box 38. f

The suction of the air in the suction trunk 27, may be regulated by means of a suction regulator slide valve 47, at the upper end of the suction trunk and a small cold air inlet opening' 48, is provided below to admit a certain amount of cold air into the suction trunk 27, to mix with the warm air therein and carried to the fan in the fan casing below. The finished feed after being carried to the head of the elevator boots 33, above is discharged through the discharge pipe 49, leading to the sacker. The floorV lines lare indicated by 'the lines A. B. and t). The eccentric shaft 4 is suitably connected by means of any suit-able and convenient gearing or driving mechanism to the driving shaft 23, carrying the main driving pulley 29. i y' As the stock-food is fedy in a thin longitudinally extending stream along the edge 3i", of the inclined shaker-board 3, and falls into the end of the mixer 6, it is, impregi nated with hot atomized molasses projected into the falling stream by means of the longitudinally extending atomizing nozzle ,Y

the stocl i'ood in the mixer 6, is further heated by the 'passage of said hot-air over the stock-food and the heating of the Walls of the V-shaped trough 20, by means of the steam heating pipes 2l. lVhen the stockifood reaches the discharge end of the mixer 6, it is discharged vertically through a vertical spout. 37, into the receiving end of a conveyer-box 36, below, and as the food falls through the spout 37, it is cooled to a certain degree by means of a cold air blast passing out of the branch a, of the cold air discharge pipe 45, leading from the Jfan casing 28.

The stock-food is conveyed to the opposite end of the conveyer-box 36, by means of a second screw conveyer, and when it reaches the opposite or discharge end of the conveyer-box 36, it falls vertically through the vertical spout 3S, where it is further cooled by a second cold air blast passing out of the intersecting cold air conduit 46, extending along the conveyer box 36. By the time the stock-food has reached the receiving end of the conveyer-box 89, it has been sutliciently cooled and is conveyed through the conveyer-box by means of a third screw conveyer which discharges the stock-food into the intersecting lower ends of the elevatorboots From the foregoing description taken in connection with the accompanying drawings, the operation and advantages of my invention will be readily understood.
